"I'm hoping to get better at playing this theremin and this song!" - asterix2k10

In front of a camera you're probably doing better than me! I tend to freeze up with just the audio recorder running... I suppose playing the Theremin isn't automatic enough for me yet.

I'm struck by how sensitive your EW is, the tiniest movements cause large pitch changes, though this is normal for analog Theremins. Have you tried sitting down to play in order to better steady yourself?

Very nice asterix2k10! That little trill you do so well around 1:00 is the most difficult part of the song for me.

Adding the ESPE01 to an EW should actually open up the low end for easier playing, I'm wondering if maybe one of the coupling caps got damaged, or if it wasn't properly retuned after the mod? Are the modded and unmodded EW's you're playing different instruments?
